Strategy X is an overhead shooter arcade game developed by Konami in 1981 in which the player takes control of a tank to advance through various stages, defeating enemies and picking up fuel.
1st Level : Defend against rotating cannons. 2nd Level : Watch out for attacking Jeeps 3rd Level : Careful! Here come attacking and shooting tanks 4th Level : Rotating cannons again, but this time against a moving background.
An audible signal warns that it is refueling time. Enter a fuel dock and receive 100-300 points. The Tank commander's life is not an easy one.
Aside from an on-going battle, he has to watch out for obstacles and rough terrain. Brick walls destroy tanks, although they can be shot away. TNT, rather nasty stuff...explodes when shot, but destroys all objects in the area. Stay off pink backgrounds. That is where the land mines are buried. They explode only on contact. Do not worry about a blue background, though. It's a slip zone like an oil slick and can be driven across. If an alien base is found and destroyed, advance to the next level of difficulty.
